Re: Multipart Request
Yea, I'm using Struts. I like some of its features so I want to continue
using it. But multipart is a mess. So, is there any way to retain the
parameters in HTTPServletRequest?
Thanks.

Multipart Request
Hi all,
I'm having trouble with the HttpServletRequest object if my post contains
multipart data. The request object loses all the parameters set from the
html form.
i.e. request.getParameter("myParam"); always returns null. If I remove the
multipart encoding from my form, I see the parameter values.
If I use the OReilly MultipartRequest, the constructor needs me to set the
directory to save the file in so I cannot make that value dynamic by
receiving it from the HTTP post. I want to receive the dir name where the
file will be saved from the HTML form.
Any ideas? Hope this makes sense.
Thanks,

Tomcat DB Connection Pooling
Hi I'm having a problem reclaiming connections in my database connection pool. I'm using the standard db conn pooling with Tomcat 5.5.9 with MySQL. I release the connection as well as close the PreparedStatement in the code after use. However, I still get errors with logEnabled set to true saying that the connection was not released. I tried the same code using a simple Statement object instead of a PreparedStatement and DID NOT see the errors. The SQL I'm running in an update, i.e. Insert statement. Are there any issues reclaiming connections from a PreparedStatement? Thanks, Dhiren
Re: DBCP ClassCastException
It works if I use org.apache.tomcat.dbcp.dbcp.BasicDataSource.
I've tried adding all the commons jars to common/lib and it still doesn't
work with org.apache.commons.dbcp.BasicDataSource. How do you get it to cast
with your own resource factory? The way I see it, it should be the same
thing if you're extending from org.apache.commons.dbcp.BasicDataSource.
Just FYI...Here's what I have in commons/lib:
commons-collections-3.1.jar* log4j.jar*
commons-dbcp-1.2.1.jar* mysql-connector-java-3.1.7-bin.jar*
commons-pool-1.2.jar* naming-factory-dbcp.jar*
jasper-compiler-jdt.jar* naming-factory.jar*
jasper-compiler.jar* naming-resources.jar*
jasper-runtime.jar* servlet-api.jar*
jsp-api.jar*

Re: DBCP ClassCastException
I'm using BasicDataSource because javax.sql.DataSource does not have methods
to set the driver class name, url, username/pwd etc. My app needs to support
different databases and the driver is loaded based on which database is
installed.
If I use org.apache.tomcat.dbcp.dbcp.BasicDataSource, then my code is not
portable to JBoss/Weblogic etc right? BTW, which jar is
org.apache.tomcat.dbcp.dbcp.BasicDataSource in?
Thanks for your response.

Re: DBCP ClassCastException
Hi Lutz,
I changed the Resource tag definition to:
I'm setting the username/password and jdbcurl using code.
I still get the same ClassCastException. Is Tomcat instantiating the
correct DataSourceFactory?
I have the commons-dbcp-1.2.1.jar in my ${TOMCAT_HOME}/common/lib
Thanks,

DBCP ClassCastException
Hi all,
I'm getting a the following ClassCastException running Tomcat 5.5.9 with
MySQL
java.lang.ClassCastException: org.apache.tomcat.dbcp.dbcp.BasicDataSource
Here's the relevant code:
*Java code:*
org.apache.commons.dbcp.BasicDataSource datasource;
datasource = (BasicDataSource)ctx.lookup("java:comp/env/jdbc/myserver");
*web.xml*
DB Connection
jdbc/myserver
javax.sql.DataSource
Container
*server.xml*
**
factory
org.apache.commons.dbcp.BasicDataSourceFactory
*...*
This same code works in Tomcat 5.0.30.
Has anything changed? Am I missing something?
Thanks.
